3D MHD simulations of planet migration in cavities and inner discs of magnetized stars
M. M. Romanova, A. V. Koldoba, G. V. Ustyugova +2
We investigate the Type I migration of planets in low-density cavities and inner discs of strongly magnetized young stars using global three-dimensional (3D) magnetohydrodynamic (M…
Eccentricity and Inclination of Massive Planets Inside Low-density Cavities: Results of 3D Simulations
M. M. Romanova, A. V. Koldoba, G. V. Ustyugova +2
We study the evolution of eccentricity and inclination of massive planets in low-density cavities of protoplanetary discs using three-dimensional (3D) simulations. When the planet'…
Accretion Funnel Reconfiguration during an Outburst in a Young Stellar Object: EX Lupi
Koshvendra Singh, Joe P. Ninan, Marina M. Romanova +14
EX Lupi, a low-mass young stellar object, went into an accretion-driven outburst in March of 2022. The outburst caused a sudden phase change of ~ 112 5 in…
Eccentricity Growth of Massive Planets inside Cavities of Protoplanetary Discs
Marina M. Romanova, Alexander V. Koldoba, Galina V. Ustyugova +2
We carry out hydrodynamical simulations to study the eccentricity growth of a 1-30 Jupiter mass planet located inside the fixed cavity of a protoplanetary disc. The planet exchange…
Measuring the Density Structure of an Accretion Hot Spot
C. C. Espaillat, C. E. Robinson, M. M. Romanova +5
Magnetospheric accretion models predict that matter from protoplanetary disks accretes onto the star via funnel flows which follow the stellar field lines and shock on the stellar…
Modulated accretion in T Tauri star RY Tau -- stable MHD propeller or a planet at 0.2 AU?
P. P. Petrov, M. M. Romanova, K. N. Grankin +3
Planets are thought to form at the early stage of stellar evolution when the mass accretion is still ongoing. RY Tau is a T Tauri type star at the age of a few Myr, with accretion…
